Abstract: A child safety device and system is disclosed that alerts one or more authorized users when a caregiver walks away from a child in a car seat or similar location, when leaving a child alone is dangerous or otherwise undesirable, such as in a hot car. Detailed logging enables a review of all times that the caregiver was detected as moving too far from the child in a monitored location. The device includes at least one pressure sensor to detect the presence of a child in a location, a Bluetooth Low Energy beacon to provide a signal when energized, and a battery electrically connected to both the Bluetooth Low Energy beacon and the at least one pressure sensor, the Bluetooth Low Energy beacon being energized when pressure is applied to the pressure sensor, and the Bluetooth Low Energy beacon being deactivated when no pressure is applied to the pressure sensor.
